'REFRIGERATOR.

Specification of Letters Patent No. 31,039, dated January 1, 1861.

To all whom 'it may concern:

Be it known that I, JOHN OSoHooLnY, of Cincinnati in the county ofHamilton and State of Ohio, have invented a new and useful Improvementin Refrigerators; and I d0 hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, making a part of this specification, in which-Figure 1 is a vertical section of my improved refrigerator. Fig. 2 is aperspective view of the lower port-ion of the same.

Similar letters of reference in both gures indicate correspondingparts.v

My invention relates to all kinds of refrigerators, ice-cliests, orpreserving rooms, ventilated and cooled by currents of air produced byice or its equivalents, and more particularly to those described inpatents severally granted to me March 13th 1855 June 16th 1857, and alsoone granted to me as assignee of Fairbanks August 12th 1856, and whichare ventilated, cooled and dried either by the interchange andcirculation or air from the exterior or interior, or both at will, andmy present improvement -relates, first, to an arrangement of an airpassage leading from the exteriorof the ice chamber of a refrigeratordown the inside from the top, thence encircling or covering the bottomof the ice receptacle and discharging at a point above the mouth of thewater escape tube in the bottom, which water escape tube is so arrangedthat the ice meltings will accumulate sufficiently to cover i the airpassage on the bottoni before it is allowed to overflow and i'uii out,thus a portion of the air passage will be submerged in the ice meltingsat all times.

My second'improvement, consists, in constructing a. double water-escapetube, so arranged that the moisture produced by condensaton in the airinduction passage, and the melting of the ice in the ice receptacle willbe carried off' and fall into the saine water cup below. Refrigeratorswhose air inlet is short and communicates directly with the whole bodyof ice are found to be defective because a greater portion of the in.-flowing air, seeking the shortest passage to the outlet will come incontact with the things to be preserved, without flowing over the ice,or receiving any cooling effects, excepting that which it'receives bymingling with air which is only a few degrees colder than itself. Hencethe necessity for controlling and directing the movements of theinflowing air. Moreover the moisture and impurities of the air aredeposited directly upon the ice itself, thus exposing its entire surfaceto the repeated and continued attacks of allv of the warm inflowing air,causing it to melt away with great rapidity, so that its cooling effectsare of short duration and very unequal in degree. This difficulty Ientirely overcome, by causing the warm inflowing air to deposit itsmoisture within the air induction passage and run off below in a watertrap-instead of depositing upon the ice; by this means it is evident agreat. saving of ice and avoidance of humidity must ensue and theinflowing air, as it flows through that part of the induction passagewhich is submerged, must necessarily be reduced' to a comparatively lowtemperature before it comes in contact with the ice, consequently thismust aid in the economy of ice, and cause the temperature of thepreserving chamber to be much colder.'

In the accompanying drawings a refrigerator is represented in a chestform with the ice at the side. The insulating sides A, bottom B, lid C,and inner lids D, may be .of any improved construction and material. Thepartition E, may be made as represented or may be of wood with the usualair passage near its bottom. 1 The ice-floor F, rests on ledges abovethe ice meltings, to prevent the ice from laying in its meltings, and toprevent the submerged part of the air induction passage, from injury 'byheavy pieces of ice falling upon it. Letter Gr, is the air inductionpassage for the flow of air, H, inlet of same, K, outlet of same. M is adouble water escape tube, with its partition N, showing the twopassages, one leading from the ice chamber the other from the inductionair passage. It, is the opening at the end of the preserving chamber forthe inclosed air to escape.

Vhen ice is placed in theice chamber, on the ice floor F, the outsideair will enter at H, pass down and through the induction passage G, andwhile in the submerged portion of induction passage Gr, it will becomecooled and dried depositing its moisture within the passage, whichmoisture rims off through the double water escape tube M, the flowingair will then pass on to the ice in the ice chamber through the exitopening K, and after becoming still more cold and dry,

water escapev tube M, so arranged as to carry off the meltings in theice chamber and the moisture produced by condensation Within 1.5 thesubmerged air induction passage with one and the saine Water cup,substantially as, and for the purposes set forth.

In testimony of Which invention7 I hereunto set my hand.
